OPB821TX Datasheet | TT Electronics

High Resolution Slotted Optical Switch OPB821TX Obsolete (OPB821TXV) Features : - Non-contact switching - Low profile to facilitate stacking - Hermetically sealed ponents - 24” (609.60 mm) minimum length wire conforms to MIL-W-16878 - TX ponents processed to MIL-PRF-19500 Description: Each OPB821TX device consists of a gallium aluminum arsenide LED and a silicon phototransistor, which are soldered into a printed circuit board and mounted in a high temperature plastic housing on opposite sides of an 0.080” (2.03 mm) wide slot. Lead wires are #24 AWG polytetraflouroethylene (PTFE) insulated, which conforms to MIL-W-16878. Phototransistor switching takes place when an opaque object passes through the slot. For maximum output signal, neither the LED nor the phototransistor is apertured. TX device ponents are processed to OPTEK’s military screening program patterned after MIL-PRF-19500. Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data. Contact your local representative or OPTEK for more information.
